Refrigeration display case

Abstract

A refrigeration display cabinet, including: a refrigeration loop having an exhaust port of a compressor, a condenser, throttling elements, a plurality of evaporators connected in parallel, and an induction port of the compressor that are connected sequentially through a flow path; a display space; and a display cabinet base in which the plurality of evaporators are superposed, wherein partition boards are disposed between the plurality of evaporators respectively, and gutters are disposed at two sides of each of the partition boards. The gutters disposed at two sides effectively avoid problems such as tilted deployment of the partition board due to installation precision or structural design, such that water from melted frost can be guided to be drained in any case. Moreover, the gutters disposed at two sides also accelerate the drainage of the water from melted frost.

1 . A refrigeration display cabinet, comprising:
 a refrigeration loop having an exhaust port of a compressor, a condenser, throttling elements, a plurality of evaporators connected in parallel, and an induction port of the compressor that are connected sequentially through a flow path;   a display space; and   a display cabinet base in which the plurality of evaporators are superposed, wherein   partition boards are disposed between the plurality of evaporators respectively, and gutters are disposed at two sides of each of the partition boards.   
     
     
         2 . The refrigeration display cabinet according to  claim 1 , wherein the gutters are disposed at an upstream side and a downstream side of the evaporator through which an air flow passes. 
     
     
         3 . The refrigeration display cabinet according to  claim 1 , wherein the gutters are grooves formed by stamping on the partition board. 
     
     
         4 . The refrigeration display cabinet according to  claim 1 , wherein the gutters are arc-shaped grooves having a uniform radian. 
     
     
         5 . The refrigeration display cabinet according to  claim 1 , wherein the partition boards and the evaporators are disposed horizontally in the display cabinet base. 
     
     
         6 . The refrigeration display cabinet according to  claim 1 , wherein the partition board is disposed between the evaporators in a non-contact manner. 
     
     
         7 . The refrigeration display cabinet according to  claim 1 , wherein the refrigeration loop further comprises a multi-way valve, and the multi-way valve is configured to selectively turn on one of the plurality of evaporators connected in parallel. 
     
     
         8 . The refrigeration display cabinet according to  claim 1 , wherein the refrigeration loop further comprises a plurality of solenoid valves disposed corresponding to the plurality of evaporators, and the plurality of solenoid valves are configured to control on/off of the evaporators respectively. 
     
     
         9 . The refrigeration display cabinet according to  claim 8 , wherein the solenoid valve is disposed on a refrigeration loop at upstream of the evaporator. 
     
     
         10 . The refrigeration display cabinet according to  claim 8 , wherein the solenoid valve is disposed on a refrigeration loop at upstream of the throttling element. 
     
     
         11 . The refrigeration display cabinet according to  claim 8 , wherein the refrigeration loop further comprises sensors disposed corresponding to the plurality of evaporators, the plurality of solenoid valves control on/off of the evaporators based on feedback data of the sensors respectively; and the sensors are temperature sensors and/or pressure sensors. 
     
     
         12 . The refrigeration display cabinet according to  claim 11 , wherein the sensor is disposed at an outlet side of the evaporator. 
     
     
         13 . The refrigeration display cabinet according to  claim 1 , wherein the evaporator comprises a first evaporator and a second evaporator; when the refrigeration display cabinet runs normally, the refrigeration loop is configured to perform the following operations circularly: all the evaporators work; the first evaporator works and the second evaporator performs defrosting; and the second evaporator works and the first evaporator performs defrosting.
